How to get GRASS GIS 7.0.5 working on Mac OS Sierra?

For some image processing tasks (especially I needed the GRASS GIS r.report command) and inspired by Peter Löwes recent blog post about the origins of GRASS GIS, I installed GRASS GIS 7.0.5 on my MAC with MAC OS Sierra. The plan was to use GRASS GIS within QGIS. The installation can be tricky 😃.

That´s why I thought, I’ll provide a short tutorial, where I gather all necessary installation steps, collected from different websites. This should help you, to have a smooth installation and to support you in avoiding certain possible pitfalls. The most important parts of the installation are well documented on http://grassmac.wikidot.com/. GRASS GIS for Mac can be downloaded here: http://grassmac.wikidot.com/downloads

Several changes and installations have to be made on your Mac with macOS Sierra to run GRASS GIS:

I. The following frameworks have to be installed:

The frameworks are compiled by William Kyngesburye and can be downloaded from his website: http://www.kyngchaos.com/software:frameworks Big thanks to William, for porting and compiling QGIS and GRASS GIS for all GIS users! The frameworks also can be downloaded from the sources below and should be installed in the order given:

II.MAC´s System Integrity Protection feature has to be disabled:

1. Restart your Mac in Recovery Mode. To do this, choose Restart from the Apple menu, and as soon as the screen turns black hold down Command + R on the keyboard until the Apple logo appears on your screen.
